Filtered count matrices for sqRNA and ST data from Asp et al 2019. Further Asp et al 2019 preprocessed matrices obtained through this workflow. Saved as: data2/all_cells_count_matrix_filtered.tsv (scRNA) and data2/filtered_matrix.tsv (STdata). For ST maps cardiac background data file grobs.list is needed. Please contact authors.
